Inertial spin Hall effect in noncommutative space    [PDF]

B. Basu, Debashree Chowdhury, Subir Ghosh
The effect of noncommutative space on the inertial spin current is studied. The spin dependent inertial force on an electron in an accelerating frame in the presence of a vector potential in noncommutative space is derived. We have taken the non relativistic limit of Dirac Hamiltonian through Foldy-Wouthuysen transformation for the electron in an non-inertial frame and moving in the non commutative space. The momentum space Berry curvature due to the presence of non commutativity is investigated. For a time dependent acceleration, the dependence of noncommutative parameter on the out of plane spin polarization is also studied which can provide a new expression for a bound of the $\theta$ parameter.
